The CLUSTER project is developing criteria and recommendations for defining "minimum composition thresholds" (see EU Directive 2009/31/EC) that captured CO2 streams from different sources must meet in order to be combined into a shared transport and storage infrastructure. Since CO₂ streams from different sources have varying compositions, the consolidation of individual CO₂ streams into a pipeline network—for example, due to differing usage times and intensities of the network by the individual sources—results in a total CO₂ stream with a mass flow that varies over time and a variable composition. The effects of these temporal variations in mass flow and composition on the subsequent “transport–injection–storage” system are the focus of the investigations in the project. The basis for these investigations is a model scenario of a regional cluster of various CO2 sources, whose captured CO2 streams are transported together in a pipeline network and injected into a geological storage site. In this scenario, the geological storage of the CO2 stream is to take place in a saline aquifer at a fictitious offshore location. Therefore, in addition to pipeline transport, the transport of the CO2 stream by ship is also considered (in the offshore section of the transport route).
